摘要: 提出一种基于模糊决策树的软件成本估计模型。该模型能够把决策树的归纳学习能力和模糊集合所具有的表达能力相结合,在软件成本估计过程中以模糊集的形式预测相对误差范围,并利用决策树的判定规则分析误差源。最后,通过软件项目历史数据验证该软件成本估计模型的有效性。

Abstract: A software cost estimation model based on Fuzzy Decision Tree(FDT) is presented.The model can combine inductive learning capability of FDT with the expressive power of fuzzy sets to predict the relative error in the form of a fuzzy set and analyze the source of error using decision tree rule.Finally,the validity of the software cost estimation model is validated with historical project data.
